World's smallest-known snake found under rocks in Barbados after nearly 20 years
BARBADOS, JUL 25 – The Barbados threadsnake, measuring just 4.1 inches, was found after a year-long search and was lost to science for 20 years, highlighting urgent conservation needs on the island.
- On Wednesday, Re:wild and Barbados' Ministry of Environment revealed that the Barbados threadsnake was found again during an ecological survey conducted in central Barbados in March.
- The rediscovery followed more than a year of searching by local authorities and conservationists, after no documented sightings since 2006 and nearly 20 years lost to science.
- During the survey, Connor Blades uncovered the tiny blind snake under a rock by a jack-in-the-box tree, examined it under a microscope, and then released it back to the forest.
- Blades described the snake as 'very cryptic,' while Justin Springer called the rediscovery 'so exciting' and said it shows something important remains in the ecosystem.
- Scientists hope this finding encourages ongoing conservation efforts in Barbados, where the threadsnake could help promote habitat protection amid severe deforestation challenges.
